Which phase of cell division is shown?
Exploring mitosis.
anaphase II
telophase I
prophase I of meiosis
telophase II
Answer:
im assuming its the same question i had, i took the quiz and the answer was telophase I
Explanation:
like i said i took the k12 quiz and got 100%
The phase shown here is anaphase. the correct option is A.
What is anaphase?Anaphase is the stage of mitosis that occurs after metaphase, during which replicated chromosomes are split and newly replicated chromosomes are moved to opposite poles of the cell.
The missing image is attached below.
The image is showing the split of chromosomes, so it is indicating anaphase of cell division.
Thus, the correct option is A.

1. A species of beetle can be either black or brown in color. The beetle's color is determined by a single gene, and black is recessive to brown. The soil in the area has become darker and closer in color to the black beetles. Which of the following will most likely occur?
Selective pressures will decrease the number of brown beetles.
Selective pressures will increase the number of brown beetles.
Selective pressures will decrease the number of black beetles.
The overall size of the beetle population will continue to decrease over time.
2. Coral snakes are brightly colored, highly venomous snakes with red, yellow, and black bands along their bodies. Another species of snake, called the scarlet king snake, has similar bands of red, black, and yellow. Which of the following describes the conditions that resulted in a large population of king snakes with these types of markings?
King snakes and coral snakes relied on similar food sources that contributed to their unique coloring.
Since king snakes with these markings were avoided by predators, they were able to survive to pass on this trait to offspring.
Coral snakes mated with king snakes often enough to produce another species of king snake with the red, black, and yellow.
Overproduction of offspring increased the likelihood that the genetic mutation leading to these bands would spontaneously occur.

You will measure and compare the heart rates of ten learners before and after
exercise. Choose ten learners in class who are willing to participate in this activity
They are the runners. Each of these runners must choose a classmate who will
measure his or her pulse rate.
Write down the question you are trying to answer in this investigation.
1.Write a hypothesis about the relationship between exercise and heart rate.
Answer:
Exercise is responsible for the increasing heart beat.
Explanation:
Exercise is responsible for the increasing heart beat because our body needs oxygen more faster during exercise. When we exercise our body needs quick energy and oxygen which can be provided by heart as well as the heart also removes carbondioxide which is produces during respiration process so the heart beat increases in order to provide energy and oxygen to the muscles.

The Haunted Forest
Once upon a time there was a family, made up of two young ones and their parents, traveling by road to road. One day the car broke down in the forest. The parents went out to get help, and so the children would not get bored, they left them with the radio on. It turned night time and the parents still did not return. Then suddenly they heard the disturbing news go on in the radio: A very dangerous killer had escaped from a prison near the forest. Hours passed and the children's parents did not come back. Suddenly, they began to hear something really loud. ¨Bang, Bang, Bang¨. They heard that which seemed to come from something hitting the top of the car. Then, the sound became louder and louder every time. ¨BANG, BANG, BANG¨. The terrified children could no longer resist. They opened the door and ran in a hurry. Only the eldest of the children dared to turn his head to see what caused the loud noise. He should have not done it though, there was a large and scary man on top of the car, who hit the top of the vehicle with something on his hands, they were the heads of his parents! The children began to run even faster and the large man began to run towards them. The children ran into the forest and so did the large man. After that day no one ever saw those children ever again, and who knows, they may appear mysteriously next to you.

Explanation:
Touch the stigma and notice how it feels. What is the advantage of this type of texture?
A. The sticky texture allows for capture of prey to help with fertilization.
B. The sticky texture allows for the exchange of carbon dioxide to assist with photosynthesis.
C. The sticky texture allows for pollen to adhere to the stigma for fertilization.
D. The sticky texture allows for water molecules to not escape from the plant, thus preventing dehydration.
Answer:
C. The sticky texture allows for pollen to adhere to the stigma for fertilization.
Explanation:
The flower is the reproductive structure of a plant. The STIGMA is a part of the female reproductive system, which is known for its function to receive pollen grains from the male flower during pollination. However, according to factual information and as stated in this question, stigmas are sticky to touch.
The major advantage of this stickiness of stigma is that it allows pollens from the male flower to be strongly adhered to the stigma in order for fertilization to occur.

what is a DNA 1 paragraph pls :))))))))))
Answer:
DNA is a self replicated material that is inside almost every living animal, and human being. DNA contains genetic codes. Dna holds genes, for example those who created you, there genes are passed on to you causing it to also be in ur DNA. It contains instructions that an organism needs to live, develope and reproduce. DNA serves as the primary unit of heredity in different types of organisms. (It might not be long enough but maybe this could atleast be used as half a paragraph)

Over the next 10 years, many of the UK’s nuclear power stations are expected to close.
Suggest how this may affect the future balance of sources of energy used for electricity production in the UK.
Answer:
Greatly affected.
Explanation:
This closing of nuclear power stations greatly affect the future balance of sources of energy used for electricity production in the UK because the burden of production comes on other sources such as production of electricity from fossil fuels, wind and solar radiation etc. If electricity is produced from fossil fuels so it leads to pollution of the environment whereas if the electricity is produced from wind and solar radiation, it is very costly but good for the environment.

Which theory directly
contradicts the concept of
absolute zero?
A. Gravitational Theory
B. Kinetic Theory
C. Matter Theory
A sample of matter experiences a decrease in average kinetic energy as it continues to cool. One would anticipate that the particles will eventually come to a complete stop. The temperature at which particles should theoretically stop moving is absolute zero. Thus, option B is correct.
What theory directly contradicts concept of absolute zero?All molecules are predicted to have zero kinetic energy and, as a result, no molecular motion at absolute zero (273.15°C). Zero is a hypothetical value (it has never been reached).
Absolute zero signifies that there is no kinetic energy involved in random motion. A substance's atoms don't move relative to one another.
Therefore, Kinetic energy because it can create heat which goes against the absolute zero. A gas molecule's kinetic energy tends to zero when the temperature reaches absolute zero.

What would happen if we didn't have a moon?
Answer:
The moon affects the angle of the Earth's tilt. ... The moon influences life as we know it on Earth. It influences our oceans, weather, and the hours in our days. Without the moon, tides would fall, nights would be darker, seasons would change, and the length of our days would alter.
Explanation:
Answer:
Simply said: Night would be a lot darker
Explanation:
The moon is responsible for a lot of things, but two that it's most well-known for is the pull is performs on the earth and lighting the sky at night. The moon reflects light from the sun, allowing us to see better at night, without assistance from outside sources- so simply said, it would be a lot harder to see. Also, the moon pulls the earth towards it, which causes more stability for the planet. A side effect of this are tidal waves.

What type of energy makes heat
transfer by conduction possible?
A. chemical
B. mechanical
C. kinetic
Answer: C. kinetic
Explanation: On a microscopic scale, conduction occurs as rapidly moving or vibrating atoms and molecules interact with neighboring particles, transferring some of their kinetic energy. Heat is transferred by conduction when adjacent atoms vibrate against one another, or as electrons move from one atom to another.
